    Now the media will go nuts about the Asian space race ...



    Chinese moon lander on the verge of launch

    China has scheduled the launch of an ambitious robotic lunar rover as soon as Sunday on a quest to achieve the first soft landing on the moon in more than three decades.

    The Chang'e 3 mission is China's third moon probe, following two successful orbiters that surveyed the lunar surface and mapped landing zones.

    Chinese officials say the mission is set for launch in early December, with landing on the moon scheduled for mid-December. China has not officially disclosed the mission's launch or landing dates.

    But an aeronautical notice issued to warn pilots of an impending launch indicates the solar-powered rover is set for liftoff Sunday shortly after 1720 GMT (12:20 p.m. EST) from the Xichang space center in southwestern China's Sichuan province.

    The launch will come in the middle of the night in China at approximately 1:20 a.m. Beijing time.

    A Long March 3B rocket will boost the probe on course toward the moon, where the spacecraft will enter orbit five days after launch before dropping to the lunar surface for landing some time in mid-December, according to Wu Zhijian, a spokesperson for China's State Administration of Science, Technology and Industry for National Defence, or SASTIND, which is managing the Chang'e 3 mission.

    The mission is China's first try to land a spacecraft on the moon - or any other celestial body - and it marks a new phase in the country's exploration efforts, which include a lunar sample return mission before the end of the decade.

    The lander reportedly weighs about 3,800 kilograms, or about 8,377 pounds, fully loaded with propellant. It's dimensions measure a bit larger than a sports utility vehicle.

    The Chang'e 3 lander will descend from lunar orbit and use rocket engines to settle softly on the moon's surface in a region known as the Bay of Rainbows, or Sinus Iridum, on the upper-left part of the moon as viewed from Earth.

    The Bay of Rainbows has never been explored by a moon lander before. The Chang'e 2 mission, China's second lunar orbiter, mapped the Bay of Rainbows in detail after its launch in October 2010.

    Once the four-legged lander touches down, the mission's rover will drive onto the lunar surface on a ramp.

    The rover has six wheels and has a mass of about 140 kilograms, or about 308 pounds, according to Xinhua. It is powered by solar energy but carries radioisotope heater units to keep the rover warm on cold lunar nights, according to a paper written by researchers at the Beijing Institute of Spacecraft System Engineering and published in Science China.

    Chinese officials announced Tuesday the rover is named "Yutu" after a campaign to solicit naming suggestions from the public. Yutu was the most popular submission, and it means "jade rabbit" in Chinese, Xinhua reported.

    The Chang'e lunar program is named after the Chinese goddess of the moon, and Yutu the rabbit is her companion in Chinese mythology.

    Anyone know the timing of this..and if it's being broadcasted on youtube (or other streams)?

    It's going to be terrible if the broadcast is on chinese youtube (yoko?), it's so laggy, internets take time to cross the great firewall.

    Edit: On the above bbc link I went down...and the comments loaded up, and sure enough, another british guy screaming his heart out saying they gave china millions of dollars of aid for this program to happen.... But it seems like they've increased the moderation after the mars launch.

    OT but the Chinese Moon Cake that they have during the harvest season called Zhongqiujie is a delight to the taste buds.

    I believe there are a variety of such mooncakes, but I had tried the Cantonese mooncake.

    Cantonese mooncakes are too sweet and no good to the body. Once a year and eat 1/4 of the cake is the maximum dosage.

    Here is a picture of the Chinese Moon Rover. The design of the wheel spokes is very intelligent indeed. It has been made in a way that it reduces weight and at the same time allows the Lunar dust to fall off as the vehicle moves forward. What I find odd is that contraption sticking out in the front and touching the ground. Are the Chinese paranoid that someone will have planted anti-personnel mines out there?

    GJ with the launch China!

    The next date to watch out for is the 6th, when the lander will be inserted into moon orbit, and then 16th, when the lander descends down to the moon.

    The robotic arm in front contains two instruments
    and

    Chang'e 3 - SPACEFLIGHT101


    I like how they have many cameras on the various stages of the craft, makes for some good photo ops!

    Here are images of the lander separating from the rocket:

    This project is very much about propaganda as much as it is about whatever else they said their stated goals were.

    actually it is a design lost in the bid....this is a product from a Shanghai based team and that ' mock-up' was displayed in the Industry Expo Shanghai 2013 last month...obviously the extended hand is some kind of ' lunar soil' sample collector...
    -------------------

    the 'winner' was also disclosed last month and was named as 'YuTu' lately...

    Thanks, and I stand corrected. So the one that actually won has the Soviet Lunokhod style spoked wheels. Cool. I guess that keeps the wheels very light and improves suspension.

    Edit:
    @shiphone
    I apologize. I wanted to respond, but hit the wrong button and ended up editing part of the post. Could you please repost?

    the 'lost' edited or the added part:

    the full broadcast of the Launch was quite long...here are the four clips (15 mins each) covering the whole process..but so far only two of them have been uploaeded...

    Another Brit cribbing about "aid" given to PRC:

    Looks like cribbing has become the national pastime of the Brits.

    china's "fixation" on the moon is i believe for good strategic and logical reasons

    (1) it is relatively nearby and they we could harvest see quick results ..compare mangalayaan -
    we have to wait 300 days to know if we finally succeeded or not ...
    they are gonna get feedback fast one or two day time frame and
    and take corrective action fast , so their learning curve is faster and they gain experience
    more rapidly - while we wait for 300 days, meanwhile they have been learning faster
    and accumulated more real knowledge

    (2) the moon contains sufficient quantity of minerals worthy of being mined
    - dont get romantic - the chinese intention is to mine
    the surface of the moon for minerals - which can be used by their military as well

    (3) by concentrating on the moon, they are focusing their objective
    and getting more intensive experience in a specific area - this will
    all come in useful as they focus on sending a manned mission there

    (4) i am not criticizing mangalayaan because the experience gained in the
    area of long-distance communications and control will be useful, but i think the chinese
    are being more deliberately focused - we can also do likewise

    (5) lets also focus on the moon - more - rather than go for too distant objectives
    if we leave the moon to the chinese - that will be another strategic blunder
    not very different from what Nehru did in 1962 by ignoring all the road-building they did
    and pretending it didnt matter
    - except this time the blunder occurs .... on the moon !!

    We were supposed to go to the moon, in collaboration with Russia But..

    So while we build a rover and wait for the gslv....

    why waste the opportunity to test out our capability to plan and execute long distance travel, which will surely be of use later, and also launch other probes for $$$!!!

    In this article the BBC have not even mentioned poverty in China with respect to their moon mission. Whereas the British are free to criticize India's mars mission and lack of social well being for poor people in India.

    The reason: Our Indian scientists have not been able to explain properly the future benefits of India's mars mission to the media. Instead they are comparing this mission with weather satellites, cyclone alerts and how to catch more fish which have no relation with Mars whatsoever.

    As long as CCP doesn't start claiming moon for itself after it lands something on it! :heh: Joking!
    Best of luck to China with the Moon Lander. More such missions from different countries can only be good for our future.

    @roma

    Chandrayaan-2 - Wikipedia, the free encyclopedia

    Mangalyaan is important cause its a window which comes only two years, also we can collaborate with NASA on this mission with their own Maven.

    Plus India should first focus on developing better rockets that'd put good payloads in our probes.
